DESCRIPTION:OPTIMAL COUPLING FOR LOCAL ENTANGLEMENT EXTRACTION FROM A QUANT
 UM\nFIELD\n\nQuantum-Nano Centre\, 200 University Ave West\, Room QNC 1201
  Waterloo\,\nON CA N2L 3G1\n\nThe entanglement structure of quantum fields
  is of central importance\nin various aspects of the connection between sp
 acetime geometry and\nquantum field theory.  However\, it is challenging 
 to quantify\nentanglement between complementary regions of a quantum field
  theory\ndue to the formally infinite amount of entanglement present at sh
 ort\ndistances. We present an operationally motivated way of analyzing\nen
 tanglement in a QFT by considering the entanglement which can be\ntransfer
 red to a set of local probes coupled to the field. In\nparticular\, using 
 a lattice approximation to the field theory\, we show\nhow to optimize the
  coupling of the local probes with the field in a\ngiven region to most ac
 curately capture the original entanglement\npresent between that region an
 d its complement. This coupling\nprescription establishes a bound on the e
 ntanglement between\ncomplementary regions that can be extracted to probes
  with finitely\nmany degrees of freedom.\n\nBased on: _J. High Energ. Phys
